• # Quiz - Factoring, ZPP, Zeros, and Max/Min

Posted by Kurt Waldner on 3/13/2020

Today in class, we took the 46 point quiz on factoring, zero product property, finding the zeros of a quadratic, and finding the max/min of a quadratic.

There is no homework.  Have a wonderful long weekend.  GO LIONS!!

• # Factoring, ZPP, Zeros, and Max/Min

Posted by Kurt Waldner on 3/12/2020

Today in class, we checked the problems on Page 245 involving finding the zeros of a quadratic and finding the max/min of the quadratic.  These are both concepts we have previously done, just called something different.  We answered any questions and reviewed in preparation for the upcoming quiz.

For homework, review for the quiz on factoring, zero product property, finding zeros, and finding the max/min of a quadratic.

• # Zeros, Max, and Min (AKA Stuff We've Already Done)

Today in class, we checked the six problems on solving quadratics.  This process was just another step in our progression.  First, we set the quadratic in standard form.  Then we factor the quadratic and, once we have the binomials, we set them equal to zero and solve for the solutions.  After going over the solutions, we discussed finding the zeros of a quadratic.  This is just solving the equation!!  The zeros are the x-intercepts of the equation.  We then found the maximum and minimum values of the equation.  Again, this is just the y value of the vertex which can be found by averaging the zeros and plugging the value back into the quadratic and solving it.  We then worked on the assignment.

For homework, complete Page 245 #46-54 (evens) and #70-80 (evens).  Quiz soon.

• # Factoring

Posted by Kurt Waldner on 3/9/2020

Today in class, we wrapped up another section of factoring.  These problems involved numerical coefficients greater than one on the squared term.  We also looked into completely factoring a quadratic (hint...factor out any common factors first).  We then spent the majority of class working on the assignment.

For homework, complete Page 244 #22-44 evens.

Today in class, we continued working with factoring quadratics with an a value greater than 1 (such as 2x² or 3x² etc.).  The notes of the two methods we were using are attached here.  We'll continue working with these on Monday.

There is no homework.  Have a great weekend.  GO LIONS!!

• # More Factoring Practice with ax^2

Posted by Kurt Waldner on 3/5/2020

Today in class, we continued to work with factoring quadratics with an a value greater than one.  We demonstrated four/five different methods for solving these problems.  We will continue to work with these problems tomorrow.  I will post notes tomorrow on the different methods.

There is no homework.

• # Factoring and ZPP

Posted by Kurt Waldner on 3/4/2020

Today in class, we checked the homework from Page 237-239.  There were two parts to the assignment.  The first part was factoring a quadratic.  Overall, we did pretty well on this part.  The second part was solving a quadratic using zero product property (ZPP).  This is basically factoring a quadratic and then setting each binomial equal to zero.  Once we finished going over the homework, we briefly started discussing factoring a quadratic with an a value greater than one, such as 3x²-5x+2.  We'll go over many more examples tomorrow.

There is no homework.

• # NO CLASS (JA Financial Literacy Day)

Posted by Kurt Waldner on 3/3/2020

Due to the Junior Achievement Financial Literacy Day, we did not have class today since all the Juniors and Seniors were involved in the activities.  I hope the students enjoyed their day.

For homework, complete Page 237-239 #18-44 Evens, 47, 48, and 58-62.

• # Factoring and Zero Product Property

Posted by Kurt Waldner on 3/2/2020

Today in class, we continued working with factoring quadratics.  Students need to remember to hone in on the factors of the product (c) and the sum (b) to try to come up with the proper factoring.  We demonstrated a situation that was not factorable (yet).  We then took the next step to solve the quadratics.  In order to do this, the quadratic must be in standard form and set equal to zero. We then factor the quadratic and set each binomial equal to zero and solve for x.  Spoiler alert...the solutions end up being the x-intercepts.  After going over some examples, we worked on the assignment.

For homework, complete Page 237-239 #18-44 (evens), 47, 48, and 49-52.

• # FACTORING!!

Posted by Kurt Waldner on 2/28/2020

Today in class, we started to discuss one of the most important concepts involving quadratics...Factoring.  Students need to really look at the problems and start looking for patterns.  The integer rules are also very helpful when trying to factor.  Essentially, we are trying to find the binomial factors of a trinomial.  There are a few ways to accomplish this.  Students can work backwards, undoing FOIL.  Students can fill in the generic rectangle backwards with the square term diagonal from the constant.  We can also set up a "diamond problem" where students need to find two numbers that add up to one number and multiply to another number.  We worked through a few examples and tried to make some connections to the intercept method of a quadratic.  Basically, we are going from Standard Form to Intercept Form.  We'll practice many more example and situations next week.

There is no homework.  Have a nice weekend.  GO LIONS!
